tìm x: x: 0,2 + x : 0,5- x nhân 2 = 12,03 19/07/2021 Bởi Aaliyah tìm x: x: 0,2 + x : 0,5- x nhân 2 = 12,03
$#Leam$ $\text{Ta có :}$ `x` `:` `0,2` + `x` : `0,5` – `x` x `2` = `12,03` `x` : `2/10` + `x` : `5/10` – `x` x `2` = `1203/100` `x` x `10/2` + `x` x `10/5` – `x` x `2` = `1203/100` `x` x ( `5` + `2` – `2` ) = `1203/100` `x` = `1203/100` : `5` `x` = `1203/500` `x` = `2,2046` CHUCBANHOKTOT ^^ Bình luận
`x : 0,2 + x : 0,5 – x × 2 = 12,03` `x : 1/5 + x : 1/2 – x × 2 = 12,03` `x × 5 + x × 2 – x × 2 = 12,03` `x × (5 + 2 – 2) = 12,03` `x × 5 = 12,03` `x = 12,03 : 5` `x = 2,406` Vậy `x = 2,406` Bình luận

$\text{Ta có :}$ `x` `:` `0,2` + `x` : `0,5` – `x` x `2` = `12,03`
`x` : `2/10` + `x` : `5/10` – `x` x `2` = `1203/100`
`x` x `10/2` + `x` x `10/5` – `x` x `2` = `1203/100`
`x` x ( `5` + `2` – `2` ) = `1203/100`
`x` = `1203/100` : `5`
`x` = `1203/500`

`x : 0,2 + x : 0,5 – x × 2 = 12,03`
`x : 1/5 + x : 1/2 – x × 2 = 12,03`
`x × 5 + x × 2 – x × 2 = 12,03`
`x × (5 + 2 – 2) = 12,03`
`x × 5 = 12,03`
`x = 12,03 : 5`
`x = 2,406`
Vậy `x = 2,406`
